Mine arrived on Saturday. Its fun, but I find it quite repetitive. The level design is very linear and I dont see much replayability unless the challenge cards are really, really diverse.
Ive only got to the second campaign and I must say I am loving the Prometheus/Covenant style locales. Its all so fresh for an Alien game.
I dont want to be too harsh with my critisism as this isnt usually my type of game. I prefer story focused single player experiences. I expect this will be a lot of fun in multiplayer.
